[Q] Battery - One (M7) Q&A, Help & Troubleshooting

Hi guys, I've a problem with my one.
Sometimes the battery percentage get stuck on a value for a long time, even if I keep stuff running (that usually drains battery). Tonight happened again in such a strange way..
The phone turned off yesterday evening at 0%, so I plugged in, turned on the phone, used another bit and than setted in plane mode so I went to sleep. I woke up in the middle of the night and noticed the green light so i took the opportunity to pull the plug (to avoid overcharge). This morning i notice battery percentage at 77% and battery stats with no app activity with cronology time on 32mins (I pulled the plug 4/5 hours before). Now I'm using the phone from more then an hour and it's still at 77%.
Is this an hardware or a software problem? I have stock rom update to lollipop version.
Do you know how can I try to solve this?

Also if i leave the phone unplugged at night it battery drops down 4/5% and in the battery stat i can see "standby 100%" with 100% of the time "without signal".. in the battery cronology wifi bar looks always active

Broken battery problem? Fast drains and incorrect capacity display

I'm worrying about my battery. The main thing is, it drains really fast. In flight mode and nothing else on it drains like 2% each hour. So overnight, most of the time it drains like 16%. Today i started with 100% in the morning. Used GPS for 1 hour, made a phonecall for 20mins in total time. My battery indicator said there was 30% left :/ I know this thing eats batteries, but this is insane. Because i noticed an incorrect display of the battery the last few days i gave it a soft reset. After the reset i saw the battery had only 4% left, not even 30%, but 4! :|
Many times when the phone is saying i have 'insert number' percentage of battery left it's incorrect. Because when i give it a soft reset, it changes the number. Sometimes i get more percentage back, and sometimes it drops.
One hour ago i plugged it on the charger, checked 45min ago, and it was still on 31% battery :| Then, like 10min later i suddenly saw a green light from my phone and it was full.
I've never had a device with a broken battery and i don't know the symptoms, but is this normal or is it likely that my battery is dying?
A little kick!

Reduced Battery backup ???

Hi All;
I have a Modaco's custom ROM (the latest) installed on my Tattoo and I noticed one issue.
Of course, I am not sure if this has been caused due to my custom rom or otherwise, but has anyone notice the ever reducing battery backup capacity in your tattoo's ??
If I charge my mobile to full capacity in the morning, by the time it is evening, the battery charge level drops to yellow and by late night, I get a warning that 15% battery is remaining.
I am connected to internet all day, either through w-lan, or through edge.
Of course, I tried enabling power save mode for w-lan and quite a few other tricks, all of no avail.
So, has anyone observed the same problem before ? If so, how did you solve it ?
Thanks
Shyam
Its normal for the battery to be drained if you are connected all day. Try turning the WiFi and Mobile Networks off and then confirm how long it lasts. My guess it'd double the time..almost
I have same problem as Shyamk
i've also noticed slightly higher battery drain when using modaco custom rom
"If I charge my mobile to full capacity in the morning, by the time it is evening, the battery charge level drops to yellow and by late night, I get a warning that 15% battery is remaining."
i find this hard to believe! i've fully charged my phone last night. woke up at 7AM and at 4PM pluged in the charger.I'm using stock ROM.
Removed modaco's rom and installef fyodor's rom. Surprise, the battery seems to last longer.
Fully charged in the morning, continuous internet usage all day, and battery is still green ;-)

Using custom modaco ROM here...
No problems at all with battery drain.
Cheers
No battery drain issues too with modaco.
You have to know that when you're on a place which has a poor signal strengh, your phone will use many battery to keep the connexion alive...

Froyo battery % incorrect?

I let my phone run down to 16% and I was planning to let it go to 10% before plugging it in to charge.
At 16% I was on wifi and browsing websites when it just turned the screen off, made a warning sound and flashed the red battery light. After about 3 sec it started vibrating non stop which made me think of the 'discharge' feature on some phones, (which quickly uses/discharges the battery..), I didn't want it to go to 0% so I pressed (tapped not held) the power button which seemed to turn it off. I turned it back on, plugged in, and it booted up showing 0% batt.
My question is, has anyone come across this before? Should the batt % be this incorrect? and why did it vibrate..
My phone has been frequently below 15% without problems (yes, it's not very good for the battery, I know). It should vibrate once when it hits 15% and display the charge message, but that's it.
Happened once though that my battery discharged from 50% to 0 in literally 1 second, don't know what happened then, but it hasn't happened again.
Sounds like either your battery shorted or the calibration on battery % was way off on your phone. Try charging it to full and see what happens the next time you reach 16%, it might've fixed itself.
The other day my Nexus turned off at 11% :/
wipe battery stats after a full charge.. guess that will solve the problem
this isnt just a froyo issue, i am still on 2.1 and my battery dies at 8% EVERY time. it turns off, and when i turn it back on, it shows 0% but it died at 8%. its been this way the entire time i've owned the nexus. i'm not rooted so i never wiped the battery log files yet....but i will soon enough.
Ya my phone dies at 20% everytime. I just ordered a new one though

Click to expand...
Click to collapse
do that.
On 2.1 my N1, first my N1 had its multitouch laggy starting at 15%, then after some day of uses it shuts down at 1%.
Your battery just need to be calibrate.

Odd Battery Drain

I go to bed last night and battery shows 50%, don't charge it, leave unplug. Wake up this morning and still shows 50%. Notice no 3 or 4g, go to put in airplane mode and won't go. So reboot, get 4g back and battery is at 5% now. Anyone have this happen before?
Maybe the phone was frozen?
Are you stock or Rooted or what
Stock. Seemed froze but if it was why the 45% battery drain with no activity?
Actually it wasn't froze because I could open apps, just didn't have data.
I think it's a good guess that the process that was reporting 50% left was problematic. There wasn't sudden drain; it was just showing the wrong battery left until you restarted it.

[Q] Phone switches off even though it showed 40% battery

Have a peculiar problem, The phone drains off faster than usual for last few days. In couple of instances it showed 40% battery and suddenly the phone got switched off. When i switch on it showed 0% battery and again got switched off. When i put on charger it was back to 40%.
Also full charged battery drained to 25% in 5 hours, earlier it used to come atleast a day. Battery also looking a bit fatty in its surface. Any pointers if this is the battery problem or any calibration issues? I use the stock kernel - 2.3.6 and this is there since few months. The problem started only few days back.
This happened to me too and it turned out it's a battery problem.
When I changed my battery, everything went back to normal.
If you know somebody who owns a similar battery, you can test it on your phone.
